Error finding module sigantures

I want to create new module on module configuration using MongoDBDriver.modl file but after installation , I am getting Message “You have successfully installed” but i am not able to see this in module configuration list and in logs i am getting error :“Error finding module Signatures”.

Do you have a developer license activated on your gateway?

Yeah…I have it and I installed that module, but
I do not know, how to use or access that module . That module contains .jar file and .xml file.

And I need to know how to use or call my Java methods in ignition, using this module.

Thank you for your quick reply.
